Complete Genome Resource for <i>Pseudomonas</i> sp. Strain WP18 Isolated from a Disease-Suppressive Soil Open
Bacterial strain WP18 was isolated in the Mississippi Delta from the rhizosphere of a healthy soybean plant growing in a charcoal rot disease patch, caused by the fungal pathogen Macrophomina phaseolina. The 16S rDNA sequence analysis demo…

Integrated approaches to maximizing maize resistance to fall armyworm Open
Fall armyworm (FAW) is a serious pest of maize causing major yield loss throughout the world. FAW management is not easy primarily due to its ability to migrate into areas lacking resistant cultivars, lack of diapause, and evolving resista…

Effects of Different Shelling Methods on Data Variability during Field Screening for Reduced Aflatoxin Contamination in Maize Open
Non-genetic variation limits the identification of novel maize germplasm with genetic markers for reduced Aspergillus flavus infection and aflatoxin contamination. Aflatoxin measurements can vary substantially within fields containing the …

QTL Mapping for Gray Leaf Spot Resistance in a Tropical Maize Population Open
A tropical gray leaf spot (GLS)-resistant line, YML 32, was crossed to a temperate GLS-susceptible line, Ye 478, to produce an F 2:3 population for the identification of quantitative trait loci (QTL) associated with resistance to GLS. The …
